| titleOfInvention | Nitrogen fertilizer solidifying method by active soil, flocculant, adsorbent composite material and fertilizer |
| abstract | The present invention discloses a nitrogen fertilizer fixation method by active soil and a composite material of a flocculant and an adsorbent. Attapulgite soil, active chitosan, polyacrylamide are used, and are mixed with nitrogen fertilizer according to a certain ratio to be prepared into novel nitrogen fixation fertilizer which has the advantages of slow release, low cost and high efficiency. The dissipation of effective components of fertilizer is prevented by using the synergistic reaction of the materials to adsorb and fix nitrogen element ions, and a fixation period of the effective components of the fertilizer and a fertilizer desired period of the growth of crops are consistent. The effective components are fully absorbed by the crops, and the dissipation or the volatilization of the fertilizer is reduced; meanwhile, due to the fact that the method effectively prevents a nitrogen element from entering water, and thereby, the purposes of controlling water eutrophication and protecting ecological environment are achieved. The present invention substitutes for the traditional fertilizer using method, and the use amount of the fertilizer can be reduced. The present invention has the important meaning for controlling the nonpoint source pollution of the water eutrophication and protecting the ecological environment. |
